Please help identifying this drama

I need help finding an old HK drama from what I believe is the early or mid 90s but could be late 80s as well.  The drama is in Cantonese and has an ancient setting similar to Condor heroes, I don't remember the names of any of the actors.  The plot mainly centers around a powerful sword which has been broken into pieces and hidden.  The main hero wields the main piece and the sword is large broadsword and black colored.  In the end the pieces are found and forged back together and they discover it's a key to an ancient cave with large crystal structures and treasures inside.  If anyone knows the name of this drama series please let me know thanks!

No, that isn't it, it's way too new.  That drama series was released in 2010, unless you're talking about another one with the same name.
